GTR is a technique for fixing periodontal issues to increase the stability and support of a tooth or group of teeth. Bacteria that get lodged behind the gums can cause periodontal disease, also known as periodontitis, which is a persistent illness. The hard and soft tissues supporting the teeth deteriorate as a result. This can occasionally result in spaces forming between the teeth and the bone. A bone transplant is a separate treatment that is frequently required to address these gaps, also known as bony defects.This Book focuses on the different types of regenerative techniques.
